Definitions

  • the invention relates to a method and apparatus for forming flakes of glass or flakes of other like material.
  • the method and apparatus are applicable equally to any material which would melt when heated and is capable of being formed into flakes. Flakes of glass and similar materials are increasingly being used for the reinforcement of plastics or other composite materials.
  • One method which has been employed in the past to form flakes of glass has involved forming a thin walled cylinder of molten glass and then collapsing the cylinder to fracture the glass film to form glass flakes.
  • the glass flakes produced by such a method are not flat or planar, and thus are undesirable for those many purposes which comtemplate use of flat or planar flakes.
  • the film can be broken up into flakes by mechanical means and the specification also described a method of breaking the film into flakes by blowing gas at high pressure in a direction so that it cuts through the film to break it up into flakes.
  • This method and apparatus system has now been used for a number of years but it involves complex arrangements of heating and cooling means about the rotor and its surroundings. Moreover the glass flakes produced are often inconsistent in size and thickness.
  • apparatus for forming flakes of material from a heated stream of molten material comprising means for feeding the stream in a downwardly direction into a rotating cup, the cup being arranged such that its opened mouth faces upwardly such that molten material within the cup is caused to flow over the upper edges of the cup and then flow outwardly in a radial direction due to centrifugal force, characterised in that the apparatus also includes a pair of spaced apart substantially parallel plates arranged about the cup such that the material leaving the cup by centrifugal force passes through a gap defined between the plates, the plates being mounted within a cyclone vacuum chamber arranged such that a vacuum is applied to the space between the plates to draw air from outside the chamber between the plates in a radial direction to prevent the molten material from touching the sides of the plate and to cool material until it reaches a solid state, and thereby pulling the material in a radial direction, keeping the material in a flat film and breaking it into small platelets.
  • the plates are in the form of two annular plates with cup mounted such that its rim lies between the plates.
  • the vacuum chamber is connected via its outlet to a cyclone precipitator separator and vacuum pump.
  • the cup has tapered sides so that its top edge flares outwardly so that the passage of the molten material up the sides of the cup is aided by centrifugal force.
  • the apparatus can be used to produce flakes of many different materials which can be molten. Typically this material will be glass but the apparatus may equally be used with materials such as basalt, ceramics such as alumina, graphite, and metals such as lead.
  • the apparatus includes means to vary many of these parameters as possible.
  • the cup is attached to a variable speed electric motor which allows the speed of rotation to be varied readily.
  • At least one of the plates is mounted so that it can be moved towards or away from the other.
  • this will also have an effect on the speed of airflow between them.
  • the speed of airflow can also be varied by varying the vacuum pull applied to the cyclone vacuum chamber.
  • the produced flakes can be treated by coating with suitable bonding agents or other chemicals by injecting an adhesion promotor or chemical either as the material leaves the cup or as it leaves the gap between the two plates.
  • the diameter of the plates will also have an effect on the flake size and thickness to be produced and this also will have to be carefully chosen.
  • variable parameters can be varied within wide ranges and all have an inter-relation to each other.
  • material to be used is chosen, it will be readily apparent to the skilled addressee of the specification as to how to vary the parameters to produce flakes of required size and thickness.
  • the method in accordance with the invention consists of feeding a stream of molten material in a downwardly direction into a rotating cup; allowing the material to pass over the edge of the cup to be forced through a pair of plates surrounding the cup in a radial direction by a flow of air passing between the plates to pull the stream of material in a radial direction to keep it flat and also to pull it to form flakes to be fed from a vacuum chamber to a collection point.
  • Apparatus 1 for manufacturing flaked material from a stream of molten material consists of a variable speed electric motor 3 mounted vertically to which is attached a tapered upwardly open, rotatable, centrifuge type cup 5 that flares upwardly and outwardly to define an upwardly and outwardly flaring top edge or rim 7.
  • the rim 7 of the cup 5 lies between two generally horizontal parallel, centrally apertured, annular extraction plates 9, 11, the upper one 9 of which is adjustable for movement toward and away from the lower plate 11 by a variable position mounting support 18 (in the direction of the arrow as shown in the drawing).
  • the two plates 9, 11 are mounted at their outer peripheries in a chamber opening so as to locate the plates within a cyclone vacuum chamber 13 which is connected via the outlet connection 15 to a cyclone precipitator, flake separator and vacuum pump arrangement 24 (shown schematically in the drawing), for generating a reduced pressure within chamber 13 and for collecting the produced flakes.
  • the method of operation is as follows.
  • the cup 5 is rotated at speed and the stream 17 in this case of glass, is allowed to enter from above via a feeder 16 (shown schematically in the drawing) at a given flow rate.
  • Centrifugal force distributes the glass evenly within the cup and pushes the glass outwardly over the cup rim 7.
  • the vacuum is applied to the cyclone vacuum chamber 13 via the outlet connection 15. Air enters this chamber via the gap 19 between the annular extraction plates 9 and 11 at a point 21 on the lower plate 11 and a corresponding location on the upper plate 9.
  • the entering air has a dual effect on the process.
  • the air rapidly cools the centrifuge cup 5 and the glass leaving the cup 5 at the rim 7.
  • the glass leaving the centrifuge cup 5 at rim 7 is located within the gap and prevented from touching the sides of the annular plates 9 and 11 by the air flow.
  • the air flow continues to cool the glass until it reaches a solid state, and due to friction upon the glass, continues to pull 14 in a radial direction, thus preventing the glass from rolling or rucking over, keeping the glass flat and breaking it into small platelets.
  • the platelets are collected in the cyclone vacuum chamber 13 and exit via connection 15 to the precipitator cyclone and flake separator, formed as filter section, of arrangement 24.
  • the size (loosely described as the diameter of platelet or flake) and the thickness of flake can be varied through a considerable range by adjusting the flow of glass into the cup 5, adjusting the speed of rotation of the cup 5, adjusting the distance between the annular extraction plates 9 and 11, for example, by means of the variable position mounting support 18, and varying the vacuum pull or velocity through the gap 19 between the annular extraction plates for any given gap by varying the amount of air flow through the extraction connection 15.
  • a range of materials can be manufactured on this equipment both in diameter and thickness without recourse to further grading, crushing or grinding operations.
  • the product produced is taken through the stages of manufacturing to packaging without being exposed to the atmosphere external to the equipment, i.e. save for air intake at point 21 into gap 19.
  • Treatment of the flakes produced by coating with suitable bonding agents or other chemicals can easily be made by injecting such adhesion promotor or chemical at point 23, or other suitable location such as point 21 within the air flow.
  • a glass stream of low temperature can be extruded by the air flow through the gap 19 with considerable force, pulling it extremely thin even at low temperature.
  • the gap 19 can be increased and the speed of the centrifuge cup 5 increased to give different parameters for the production of flake.
  • the process lends itself to manufacture of flake of various sizes from many different materials with varying viscosities and melting points.
  • the apparatus will produce that material constantly within very fine dimensional limits.
